Description

Semi-hermetic twin screw compressors for installation with external oil separator. Specifically design for refrigeration applications at medium and low evaporating temperatures. Refrigerants: R22, R407C, R404A, R507. 40¸250 HP (MT) or 30¸230 HP (LT) for SW 40¸80 HP (MT) or 30¸50 HP (LT) for ultra-compact SRC-W modular screw compressors. Capacity control (SW compressors) achieved via a hydraulic system and a slide valve. The capacity control can be either "4-steps" or "continuous" type. Capacity control (SRC-W compressors) achieved through a by-pass system. "3-steps". Electronic motor protection device: motor temperature monitoring (oil temperature, motor rotation direction and phase failure monitoring standard for SW, optional for SRC-W). ECO port for increased performances and efficiency. Liquid injection or connection to an external oil cooling circuit to widen the application range at higher discharge temperatures (see Application Limits). Up to 6 compressors can be installed on parallel compounding. Oil line kit provided with: solenoid valve, sight glass and filter, flow switch with electronic controller and electrolytic condenser (all components supplied loose). Special motors with different power supply available.
